Can I become a member of your team? because the idea itself is very close to me. And I would like to contribute to the development of the system.
I think if you have skills that can really help the team then why not. Contact the project administrator and discuss this in person.
judging by the information on the website the project and so has a fairly successful and experienced team, but in any case you will be able to join the project after the launch of the platform.
